Definitions

  • the present invention relates to an improved drive chain for cycles, in particular bicycles.
  • Bicycle drive chains of the type currently used consist of an alternation of reciprocally pivoted outer an inner links.
  • the pivoting is realized between a pin solid with the plates of the outer links and a core solid with the plates of the inner links.
  • a roller which come into contact with the bicycle chain wheel.
  • the link plates can have various types of configuration. A chain of the type outlined above is for example described and illustrated in British Patent Application No. 2 000 846.
  • the object of the present invention is to embody a drive chain for cycles that is lighter-in-weight and constructionally more straightforward than the chains of known type.
  • the present invention embodies a drive chain for cycles of the type comprising an alternation of reciprocally pivoted outer links and inner plates, wherein the said pivoting system comprises a pin fixed to the plates of the outer link on which the inner plates are directly articulated, there being also a roller, rotating on the said pin, which is intended to be engaged by a chain wheel.
  • drive chain of the invention is indicated overall by 10 and comprises an alternation of reciprocally pivoted outer links 11 and inner links 12.
  • the pivoting between the links 11, 12 is implemented by a pin which in the example shown has the form of a core 13 fixed to the plates 14 of the outer links 11 onto which the plates 15 of the inner links 12 are directly articulated. Between the plates 15 there rotates on the core 13 a roller 16 which holds the plates 15 in place and which also serves as a transversal spacer element.
  • the rollers 16 are intended to be engaged in a conventional manner by a chain wheel (not shown) of the bicycle wheel.
